ABSTRACT:
A floor treatment machine including a squeegee assembly having a squeegee blade adjustable for a desired angle of incidience between the blade and the floor. The squeegee assembly is pivotally mounted to a bracket for limited rotation about the longitudinal axis of the machine for tracking variations of the floor surface. The bracket to which the squeegee assembly is pivotally coupled in turn is swivel-coupled to a lifting platform by a pair of spaced support arms, each pivotally coupled between the lifting platform and the bracket to permit the squeegee assembly to follow behind the floor treatment machine as it changes direction. The lifting bracket is pivotally coupled to the machine frame and is coupled to squeegee elevating and lowering means including a compressible linkage for holding the squeegee in an operating position with a predetermined adjustable pressure of the squeegee blade against the floor surface while permitting rearward tilting of the machine with the squeegee in the operating position.
